Well here's an interesting bit of trivia that I never knew. Believe it or not, SEGA has two different colors for their logo. They have an international version, as well as a Japanese version. You can see both above, with the Japanese version using a lighter shade of blue. This information was confirmed by Sega of America’s director of production Sam Mullen, and its been a thing since the early 2000s. Now as to why SEGA does this, there's no official reason!
